Find out how  many teenagers and how many parents were questioned ( “More Information”)

Consider the following questions:

• Do you think this survey is representative?
• Which parameters are important?
• Is there any possibility to measure the representativity of a survey?

Stelle den Parameter auf 95% bzw. 0,95 und lasse die Wahrscheinlichkeit p bei 0,4. Wie verändert sich der Erwartungswert (expectation value) wenn man den Stichprobenumfang erhöht? Erinnere dich auch an die Formel E(X) = np

Set the Parameter on 0,95 and set the probability p on 0,4. Can you detect any change in the deviation (Abweichung) of the confidence section?
